Abstract (en)

[origin: EP0833127A1] The invention provides an angular-velocity detection apparatus, comprising a substrate (22), a vibrating body (26) provided on the substrate (22), the vibrating body (26) being capable of displacing in a vibration axis direction and a detection axis direction which intersect at right angles to each other, vibration generation means (33) for vibrating the vibrating body (26) in the vibration axis direction by applying a driving signal, and displacement detection means (34) for detecting the amount of displacement of the vibrating body (26) when the vibrating body (26) is displaced in the detection axis direction on the basis of the angular velocity along a detected axis intersecting at right angles to the vibration axis and the detection axis in a state of the vibrating body (26) being vibrated in the vibration axis direction by the vibration generation means (33), which is characterized in that corrective-vibration generation means (35) for causing the vibrating body (26) to vibrate for correction in the detection axis direction is provided. The angular-velocity apparatus makes it possible to reduce leakage vibration applied to the vibrating body (26) and to accurately detect the angular velocity OMEGA . <IMAGE>
